SE A1662 no power after replacing screen and battery
i am trying to fix an SE 1st generation for use as a daily driver, 1st display i forgot to unplug the battery for connecting/disconnecting 2nd display i was careful and i disconnected the battery if i wanted to remove/install anything so i have 1 display with a broken lcd and one which bootloops the device i have run some tests with the two displays
1st display all buttons work (unable to test volume buttons due to bad lcd)
2nd display no backlight, lcd or anything the phone bootloops
i disconnected the front camera on both and got a similar result phone booted up on the 1st display and nothing happened with the 2nd
i had concerns about long screw damage due to me just not knowing what i’m doing
from what i tested i can guess its either long screw damage or a faulty display (both screens and the battery are from fixit)
some notes about the phone’s condition:
it was dropped several times, was used by a smoker, was used for light tasks (solitaire, mail, had a bent corner that i fixed with a hammer and a screwdriver very carefully,
had a battery problem at the time i received it

If you can, upload some pictures (add them to the original post). Specifically around the connectors (both battery and display). Gently peel up whatever foam or stickers. This could be long screw damage, but you're not getting the same behavior with both displays and based on the not disconnecting the battery for display removal, I would think that fallout from this is more likely to be the problem.

I think you are right, I posted the connectors of the display with a bad lcd

4th image is of the screw hole next to the volume and vibrator button cable I’m unsure if what is in the hole is LSD or something else, from my research it appears so. Then why is it still able to somewhat boot?

@Nas Probably should have specified I meant the board side of the connectors (d'oh). Although the LCD side can also be helpful to depending. But really they look okay?
Also your screwhole looks fine. So I would say no LSD. Which is good. Because that's one of the less fun board things to fix in my opinion. If it was LSD, usually you would see torn up copper at the bottom of the screwhole. But I just see the top of the PCB. Which is what I would expect.

Positioning the phone just right reveals some copper but not torn up like you described
